Checked Exceptions vs RuntimeException

user6368010Jun 30 2016 — edited Jul 1 2016

Hello,

I just read the oracle documentation about Exceptions.

The Catch or Specify Requirement (The Java™ Tutorials > Essential Classes > Exceptions)

The definition for Error is clear, but the definition for the checked Exceptions and RuntimeException are confusing because therorically we can always recover from an Exception.

In doc from Unchecked Exceptions — The Controversy (The Java™ Tutorials > Essential Classes > Exceptions):

"Here's the bottom line guideline: If a client can reasonably be expected to recover from an exception, make it a checked exception. If a client cannot do anything to recover from the exception, make it an unchecked exception."

For example, NumberFormatException is RuntimeException but we often recover from this situation by asking the client to enter a valid number, isn't ?

So, how could we differentiate ?

Thank you

What browser(version) and OS (version) are you working with?

I can not reproduce what you are describing using Win10 and the latest Chrome. Right-Clicking on that table demo shows me a context menu for sorting.  It does not select a row, or do any other selections.

Hello,

I thinks you need a uniqe Key for the rows.

self.dataprovider = new oj.ArrayDataProvider(deptArray, {idAttribute: 'DepartmentId'});

Thanks

Hi John,

I am using the lastest version of Google Chrome on Ubuntu 16.04.

I do get the context menu, but if I start hovering over other rows it starts to select -mark on yellow- these rows.

Hi Hamed,

I have a unique key for the rows, I get the same right click selection behavior on the cookbook link posted before, I thought this was an expected behavior from Ojet tables.

I tried it with Firefox 53 on Ubuntu 16.04 with no luck either. It worked as expected on W10 using the latest version of Chrome.

Hi,

Can you please share your code?

Thanks

Sorry for the late response,

I could share it, but what is weird is that the cookbook example doesn't work as expected either, I am not sure if my OS is the reason for this discrepancy. As I said before, the cookbook example works fine on Windows 10 but not in Ubuntu 16.04, at least in my computer.

Thanks,
